After the Volumes of Hanoi, I tried a stereographic projection ball. I checked on it after about 90 minutes to find it making another mess. Wish I had checked it sooner. I don’t know if the base moved or what caused the problem. When I tried it again some weeks later, I  scaled the design […]

I am back! The semester got hectic and then the time right after the semester was too… Before things get hectic again, I want to share some posts about some of my 3D printing adventures during the past three months. After my last post, I printed the Volumes of Hanoi. The first parts I printed […]

Well, the dodecahedron did not turn out. It got off in the middle somewhere and never recovered. I came in the next morning to find a nice bottom half and a big tangle of messy strands of plastic all over the top and sides. According to a web entry, this model printed without supports on […]

After telling Cura to use a raft and put in supports everywhere, I was able to print a knot! I got a very nice 5_1 knot. I also started a dodecahedron printing.

My basic SD card holder printed nicely. It only holds the cards loosely, but that is good enough for my needs. I figured I could put this holder into an envelope or something like that to keep the cards from falling out, but it turns out that it just fits into a paper clip box. […]
